In order to withstand the thermal, mechanical and chemical effects encountered under operating conditions, it is often preferred to make a coating suitable for the operating conditions, rather than replacing the entire material. There are many coating methods such as melting, electrochemical, chemical, thermochemical and mechanical methods. When materials need to work especially in high temperature conditions, coatings with ceramic-based components are preferred, but very special technologies and devices and high temperature and pressure are required to make these coatings. For these reasons; In this study, the AISI 304 stainless steel material surface was coated cost-effectively, without using expensive and special devices, by thermochemical method using Al2O(3)+SiO2+ZrO+B4C+Ti+Al powder cermet material mixture in an atmosphere-uncontrolled and pressure-free heat treatment furnace. To determine the substrate surface quality, the materials were prepared with 600 and 1200 mesh surface quality before coating. The changes in structural and mechanical properties of the coated materials were examined. At the end of the investigations; It has been determined that coating can be done successfully even in a simple oven, that the coating undergoes deformation along with the material during the mechanical test and changes shape without breaking/separating, and that the coating improves its mechanical properties. After cermet coating; it was determined that there was an increase of s 65% in tensile strength, s + 32% in yield strength and s 66% in hardness, while there was a decrease of s 1% in elongation. It has been determined that time is very important in the coating process, and as time increases, the properties get better.
